My list:
W55 (need shifter, fork, bearing carrier)
Nite parts bell housing
Rt142 slave
Custom clutch line (as it moves slave to drivers side)
custom clutch (depends on flywheel, but basically a re-spline of a 4age clutch will do)
Custom cross member
Custom tailshaft (or front half from ra40(?) And rear half from which ever diff you're running)
There is a bit to it, but re-sale is usually good.
Will.
